AT&T Number sync question

I have the AT&T S2 3G but with my Nexus 6. I realize now that of course my Nexus doesn't work with NumberSync so I am stuck with auto call forward option. I am debating of move from the N6 to maybe a Note4 least until I can get a S7 when it comes out. Here are my questions,
1. How does text messages work, Will they both show up on the watch and phone? For example if I leave my phone behind and I get a text and respond on 3G just with the watch. Will I see my reply on my phone when I go back home to use it? So my text log will be the same on watch/phone..?
2. One last one is getting phone calls, I am assuming that with the on BT only my phone will ring. The watch will ring only when its on 3G mode right?
Sorry if these are dumb questions, the guy at the AT&T store couldnt give me a for sure answer at all.. I'd rather trust you guys here instead.

Actually, it's easy to get numbersync to work. you just need to update the imei in att system with an att phone that supports volte, even if you're not actually using that phone. . Did it with my moto x pure.

I tried that with my wife's S6. But soon as I put my sim back in the N6 I got a text saying it was turned off. Can you explain on what you did exactly?
Thanks

I called them and said I was using an HTC desire 626, and changed the imei to match an att 626, then put the sim into my moto x pure, and set up number sync. Maybe the n6 is just a jerk when it comes to that? There is a soc code that care can add "numbersync on" that MIGHT help with the issue.
---------- Post added at 08:30 PM ---------- Previous post was at 08:29 PM ----------
I actually have the 626, and waited like an hour before swapping sims.

Was the HTC desire 626 an extra phone? Guessing that I will need an older phone to lie about my IMEI #.

Yes, I had to finance them to get the credits for porting my numbers over with directv and unl. I may have a damaged HD voice phone at work that you could use the imei from. (All legit, phone with cracked screen used as a trade in to "recycle" ). PM me if needed.

I have an iPhone 6 Plus and an international Samsung Galaxy A8 with no HD Voice or VoLTE. Since my SIM card is tied to an iPhone plan, Numbersync works no matter which phone I have on me. For example, if I have the SIM card in my iPhone 6 Plus, I just leave my Galaxy A8 connected to the charger with WiFi connected. If I am away from home, my Gear S2 3G is able to connect to my Galaxy A8 remotely to receive notifications, and it will ring if I receive a call on the number tied to the SIM card in my iPhone 6 Plus.

Thank you for the offer paoloroesekel. I just read last night that with AT&T is giving FREE S2 with any galaxy phone and I am due for an upgrade. So maybe time to get note5.
I just have 3days left to return my current S2.
Thank you though!

You're welcome! We weren't made aware of that promo here. Lol. Time to offer it to people!

Just sent you a PM about that old IMEI, some news sites say the watch is free but AT&T is saying its now.

There is now a work around for the watch not being free with a purchase of a galaxy device. . Make sure they look up the coupon code

Thank you! I got the NumberSync to work perfectly. However I seem to have lost VM. Did that happen to you?
And thanks for the heads up about the promo. I still might just keep the N6 now that I got NumberSync working.

My voicemail seems to still work. We're you actually utilizing the watch number? Have you tried calling 1 and setting it up again?
---------- Post added at 03:11 PM ---------- Previous post was at 03:10 PM ----------
I'm glad numbersync is working now for you. Was it the imei?

I was trying to have the same VM as the phone. But for whatever reason if the watch has numbersync on it get a busy signal. Ive tried messing with the actual voicemail number on the watch itself to match the phone but no go. I may have to call ATT again but dont want them to tell me that me IMEI dont match.

As far as numbersync goes are yall getting it to work with messages too? I can only get calls....tier 3 or 4 engineer dude said it's only supported fully on s6 active and S5 mini.

This post is from 2016 so Idk if AT&T's numbersync technology has changed since then.
Have you ever tried getting numbersync to work on a Huawei phone ?
I just bought a Huawei Mate 20 X EVR-L29 (c636 Asian international version) & I had to switch from Verizon prepaid to AT&T prepaid , I also have a LG Watch Sport on AT&T prepaid, I am interested in switching to post paid plan if I can get numbersync to work & Huawei Mate 20 X to my LG Watch Sport.
Do you think the method that you provided will still work even 2-3 years later & on a Huawei phone?

Anyone using a Gear S2 3G on a different carrier than your phone?

Since VZW doesn't appear to be on board with the launch of the Gear S3 tomorrow I am looking to get it on T-Mobile.
Anyone here using an S2 3G on a different carrier than your phone? If so, how's the compatibility? Seamless? Can you receive calls made to the handset on the Gear when you leave the phone at home? Texts, etc?
I know I can connect via Bluetooth when using the devices together. I just want to be able to receive calls and texts made to the S7 when I leave it at home.
Thanks

I want the handset calls and texts to forward to the Gear when I leave the phone at home, i.e. Cycling, working out.
I pretty much want it all to work the way it would if they were on the same carrier. I don't have a problem using Gear data as a stand alone. Just want notifications to go through.

It will connect. Forwarding works, but as but what I've learned is check to see if the gear is using ur phones number or the gears number.

Im not sure to be honest. The S2 has a, esim?, i think its called. Basically the sim is built into the device. I think that limits the carrier its tied to.

I'm not sure, either, about taking it to T-Mobile. I think you have to have ATT unlock it. Are you the original owner? My understanding it that only the original owner can unlock it. As for the cost of service on T-Mobile, if you don't have a phone on T-Mobile, it's about $19/month for unlimited calls, texts, and 500MB of data on your watch. My Note 4 is on Sprint, my S2 is on T-Mobile. It is a T-Mobile model. I'd go into a T-Mobile store and see what they say. Let us know.

Did you buy your S2 new or even refurbished off of Amazon or something? You might be able to activate it online if this is the case. I went to the T-Mobile store to activate mine, as I was buying it from a guy on Craigslist. I wanted to also make sure I could activate it. That it was paid for and so on. That worked fine in the store. I had already had a T-Mobile account for my original Gear S. When I got home, though, I had trouble connecting my S2 to my Sprint Note 4. I had to do a factory reset on the watch a couple of times to make it work. It was scary at first, because when I went to set it up, the only screen I could get to on my watch was a set up screen. I couldn't get past it. That's when I did the factory reset on the watch. And then reset it some more. Finally I was able to connect it to my Note 4. The original Gear S has a nano SIM card, so you can swap it out. The S2 has an "e-SIM" card. It's sort of hard wired into the watch, I guess. The moral of this long post is, I'd probably go into a T-Mobile store to get it set up on their service. They should also be able to help you get it connected to your phone.

Does Verizon's wearable plan consist of both a cellular and a data component? Or is talk and text only available using VoIP (data)?

NumberSync S3 on AT&T

I'm unable to get it setup on my Note4. I get the incredibly useful message "Backend error" from the AT&T site after I enter the sync code on their site.
Is this a temporary issue you think, or is it just the usual incompetence of an inept software developer who can't be bothered to give meaningful results to help narrow down the cause of an error?
Is it working for everyone else?

Yep, getting the same error message. Hope this is temporary!

I was having a similar issue. On my Gear S3 when trying to get the sync code, it kept giving an error message. Finally after 9:30 central time I was able to generate the code and get it synced. I think the system was overloaded with all the at&t pre-orders being delivered yesterday.

Anyone have AT&T S3 but linking to S7E 935F International phone? Keep trying to set up Numbersync but it connects to my wife's 935A. It won't see my phone. I am running Hydra Rom but the watch is connected with Bluetooth no problem.

For numbersync to be setup, you have to have a username for myatt for that exact phone. Then it will allow you to setup numbersync if that phone is HD voice capable.

I set it up on my Axon 7 without any problems.

Just tried again, same error message

According to AT&T International S7E (Exynos) is not compatible with LTE Frontier watch on AT&T due to no HD voice? Can use Bluetooth, but not the Numbersync. I'm pretty PO'd right now as that was why I bought it.

Anybody getting this to work yet?

I have not been able to get it to work. I am using an unlocked tmobile note 4. When I called I was told it was because it was not an at&t phone. What if I change the build prop to 910A from 910T? Would that be enough for it to work? Dont want to try and mess things up.

Hi I'm new to this forum. Like OP, I also have a Note 4 ATT LTE and had the same Numbersync error. Here is how I resolved my issue after extensive research:
1) Make sure to enable HD Voice on your phone if supported (for Note 4: Settings->More networks->Mobile networks->Mobile data->check Enhanced LTE Services (mine was unchecked)
2) Before even attempting to sync via Numbersync, make sure that your cell phone number is set as primary in My ATT account. I didn't have a primary number set, so I tried making the Gear S3's number primary (when I was prompted to add one) and it didn't work properly. So I learned it's essential your PHONE (the one you intend to connect with S3) is set as primary, NOT another phone/tablet/wearable line in your account.
3) After all the initial errors and hassles thereafter, I just reset the S3 after following my above instructions and the sync was seamless and I was up and running.
Hope this helps...it certainly worked for me!

The red pointer is for the chronograph function. It does not move unless you tap it to start the chrono. Bad design in my opinion.

Soo no one here might have an iPhone they were able to get numbersync to work on with the leaked iOS app?

Has anyone got Numbersync to work on International S7E 935F?

I have number sync working with my Nexus 6P, spent about an hour in the AT&T store working with the salesperson that sold me my Frontier. He was under the belief that it was tied to IMEI numbers so he supposedly cloned my wife's IMEI number to my 6P which didn't work. I told him that I read that HD Voice/VoLTE had to be enabled and because I had a Nexus 6P that was the problem. So he called support and asked them to enable HD Voice on my line. While he was doing that I was googling, found this thread: https://forums.att.com/t5/Device-Features/Nexus-6P-No-HD-Voice-and-Wifi-Calling/td-p/4346076 and followed this guide:
Navigate to Settings > More > Cellular Networks and enable the toggle switch for "Enhanced" 4G LTE Mode. However, if the toggle is missing then follow the steps provided below:
Launch the Dialer app on your phone, and dial*#*#4636#*#*.
Choose Phone information.
Enable or select VoLTE Provisioned Flag.
Restart the phone.
Go to Settings " More " Cellular networks and toggle the switch for Enhanced 4G LTE Mode, and the HD Voice calling feature should now be activated on your device running Android 5.1 and above.
Click to expand...
Click to collapse
I enabled the VoLTE option, restarted my phone and sure enough when I went back into the MyATT webpage I was now offered the ability to enter in a sync code and it worked. He was never able to get support to enable HD Voice on their end. Going back into the setting it shows that VoLTE isn't active, I have no HD Voice option or feature in the Enhanced 4G LTE options at all but my number is indeed synced. I left my phone at home, walked the dogs and made 2 phone calls and the number did go over as my cell number.
Now the other thing he mentioned that should work is to use an approved AT&T phone that has HD Voice capabilities enabled. Then if I were to put my SIM in that phone, wait for the MyATT webpage to update showing that this other phone was tied to my number, then perform the number sync at this point it should also work, once it's enabled it won't go away according to the ATT rep. I didn't need to do that so I can't confirm but it sounds reasonable.

SM-G955U ATT Unlock Using Tmobile IMS Issue (Help)

Honestly just get the T-Mobile version or whatever version you will be using >50% of the time. Nobody has gotten any one carrier successfully flashed to another carrier yet. Lots of talk about it with zero proof in any threads. It could happen today or maybe never. Seems like an expensive gamble for a maybe with the way Samsung changes things every phone release.

That you can get at least the most basic features without having to buy new devices. Eventually there will be one standard but as of right now there's like 7. T-Mobile has their own. Samsung has their own which Sprint and T-Mobile is hopping on board with. Google has their own. AT&T has their own. I think Verizon uses the most open standard(Block C rules did this). Right now it seems Samsung will win this due to the volume of devices they sell.

Visual Voicemail for unlocked U1

I've always downloaded Samsung Visual voicemal from APK mirror for all unlocked samsung devices, even my note 10. I installed it fine on the note 20 but when i try to open it it says not supported. Any idea for a visual VM program? Voicemail is practically useless without VVM.

I can't find the Verizon VVM that is compatible either. I'm looking for the APK if anyone figures it out.

Transferred Tmo VVM app via Smart Switch from previous S10+. Working fine on unlocked N20+

I downloaded version 12.1.00.35 from the Galaxy store on my US unlocked Ultra and it works just fine. I am AT&T for cell service , just moved sim from note 9 to this phone.

not sure if this is applicable for your situation but, i have a note 20 ultra unlocked (US Version) using google fi.
I downloaded the google phone app from APKMirror then installed (one of the newer apk's), set as default, then i installed an "android go" version of the phone app from APKMIrror as well, and now i have visual voicemail, it stuck after a reboot and is working for visual voicemail (transcript appears and seems accurate). It is a bit funky as it hangs when i try to play voicemails over the earpiece but it seems like playing it via speaker phone is fine. There is also a toast notification that pops up every time i open the phone app that says the device is not compatible and phone calls may not work properly, but it seems fine. YMMV!

I didn't do anything, I mean, I put my sim card in the phone, turned it on, logged in with my google account, did the software update they pushed, rebooted. etc..... I did dial into my voice mail and checked everything and it was working, then I opened visual voice mail and it worked, I didn't do anything to make it work.
